Central problems of theoretical macroeconomics can be analysed with th
e aid of aggregate demand and supply curves. This approach is necessar
y if distribution theory is to be seen within a comprehensive framewor
k. The present article deals with the incorporation of modern macroeco
nomic distribution theories into such a framework. Several models are
discussed: neoclassical, Keynesian and bargaining-power in both the pr
oduct and labour markets. Finally, we synthesise a neoclassical model
embodying the different approaches.
